通道、涵洞和圓管涵施工方案

一、   工程概況：略
二、   施工準備：
（1）、清除雜物，整理場地；（2）、清查安裝主要的施工機具；（3）、安裝好施工現(xiàn)場水電供應設(shè)施；（4）、合理組織施工，做到責任明確，分工合理；（5）、準備足夠的施工所需用的材料。
三、   施工方案：
（一）、通道及鋼筋砼蓋板涵：
  1）、施工放樣。仔細對施工圖紙進行復查，領(lǐng)會設(shè)計意圖。根據(jù)圖紙確定的構(gòu)造物的位置和標高，準確計算結(jié)構(gòu)物中樁坐標和軸線方向，然后根據(jù)計算的具體位置進行施工放樣，為便于開挖后的檢查校核，基礎(chǔ)軸線控制樁應延長至基坑處加以固定。放樣完成后，根據(jù)基礎(chǔ)的結(jié)構(gòu)尺寸放出結(jié)構(gòu)基礎(chǔ)的邊線，申請駐地監(jiān)理工程師復查，得到確認之后，方可進行基坑開挖。
2）、基坑開挖。
A、     根據(jù)現(xiàn)場施工設(shè)備條件和施工環(huán)境，基礎(chǔ)開挖采用挖掘機開挖，人工配全修理；開挖時派出專門的測量人員及時測出其基底高程，防止超挖現(xiàn)象發(fā)生。對于有地下水的區(qū)域，基礎(chǔ)開挖時在基坑四周挖集水溝，以保持良好的排水，確保在挖方的
Channels, culverts and pipe culvert program

1, Project Overview: A Brief
Second, construction preparation:
(1), debris removal, site preparation; (2), installation of major construction equipment inventory; (3), installed at the construction site water supply facilities; (4), reasonable organization of construction, be accountable, and reasonable division of labor; (5), to prepare enough materials required for construction.
Third, the construction program:
(A), channel and reinforced concrete Culvert:
  1), loft construction. Carefully review the construction drawings, understanding of design intent. Drawings to determine the structures according to the location and elevation, accurate calculation of structure coordinates and the axis of pile, and then calculate the specific location for construction setting, to facilitate excavation of the check verification, based axis control should be extended to the base of pile Pits to be fixed. Setting is completed, according to the structure based on size of the structural basis of the sideline release, resident supervision engineer for review, was confirmed before proceeding with excavation.
2) excavation.
A, construction equipment, according to the site conditions and construction environment, based on excavation by excavator excavation, artificial with all repairs; excavation specialist surveyors sent out its base elevation measured in time to prevent the phenomenon of super-dig. For ground water areas, based around the excavation pit dug in the gullies, in order to maintain good drainage, to ensure that excavation of
